Who? When I think of the leaders of the American film industry I think of Spielberg, Scorsese, Tarantino, James Cameron, Clint Eastwood. What anti-Americanism? I see many movies every year and still love the U.S.
Just to go through a few.
Spielberg who chastises the Boy Scouts because they won't let homosexuals become Scout masters and probably supported the court fights, that ultimately lost, to force them to. Ever heard of the American concept of free association.
Scorsese who directed a blasphemous and direct slap to millions of Christians with the last temptation of Christ.
Tarantino who has for the most part produced nihilistic violent filth that is hailed as art. I wouldn't be surprised if tarantino has a picture of "piss Christ" hanging on his wall.
On and on. Modern hollywood isn't your father's Oldmobile, these days.
